Final answer:
Salivation in response to food being placed in the mouth and an eyeblink response to a puff of air are examples of unconditioned stimuli and unconditioned responses.
Step-by-step explanation:
Salivation in response to food being placed in the mouth and an eyeblink response to a puff of air are examples of unconditioned stimuli and unconditioned responses. In the case of salivation, the food is the unconditioned stimulus (UCS) that naturally elicits the unconditioned response (UCR) of salivation. Similarly, the puff of air is the UCS that naturally elicits the UCR of blinking.
